Theses and Dissertations
The upper Red River Formation in North Dakota comprises a subtidal/intertidal facies overlain by three evaporitic sequences of four lithologic units each, labeled "P," "R," and "F" in stratigraphic order. Four porosity zones are recognized in the upper Red River: the subtidal/ intertidal facies forms one porosity zone, and each evaporitic sequence contains another. Each unit in a sequence, as well as the sequence itself, is thinner and less widespread than its preceding counterpart. All strata are laterally continuous across the main part of the Williston basin in North Dakota, but, the porosity zones eventually disappear to the east as …
